Abstract

Mature fruits of coroba (Jessenia polycarpa Karst), a wild palm from Cedeño municipality (Bolívar estate, Venezuela), harvested on July 1999, were washed, scalded, decorticated and then the mesocarp was separated. It was dried (70 ºC by 12 h), grounded and extraction process with n-hexane was applicated. The extract was distilled for to obtain the crude oil free of solvent. Physicochemical characteristics of crude oil from Coroba mesocarp were determined by means of Venezuelan official methods (COVENIN). The results showed: free acidity 0.72 % (as oleic acid); iodine index 48.2 (cgI₂/g); peroxid value 2.32 (meq O₂/kg); refraction index 1.4465 (at 25ºC); saponification number 198 (mg KOH/g); phosporus content 183 (mg/kg). The fatty acids composition was determined by gas chromatography. The major fatty acids found were: oleic acid (46.06 %), palmitic acid (28.56%) and linoleic acid (18.04%). The Coroba mesocarp is a potential raw material for Venezuelan oil industry.
